Won't work on our 1100's Brian. Alot of carbs have a drain on the side of the bore where the drain screw goes. Not so with our carbs though. The fuel actualy drains through the middle of the screw. You have to find something like a brass screw with the same threads, then drill the center of it and JB Weld a hose barb into the hole and thread that into the place where the stock drain screw normaly goes and attach your clear hose to that.
Actually you can do it..just "thread" the right size plastic tube into the carb's drain hole..a plastic tube will actually tap itself as you turn it into the hole and seal up tight..do all four and then fill the carbs. It helps if you shave the end of the the tube a bit to get it started.
